B and C are both rational numbers
hope that this helped hon :)
First, simplify the inequality by getting the x term with a coefficient of 1.
Divide both sides by -7. When you multiply or divide an equality by a negative number, you flip the inequality sign the opposite way.
-7x / -7 < -21 / -7
x > 3
In set build notation is would look like this: {x | x > 3}
Which would be read as "the set of all x, such that, x is greater than 3".

For #1 you have to make the denominator the same so it will be 4 and 8/16 and 5 and 9/16 Then subtract them. For #3 you divide 175 by 7.
For #4 you do the number of days and multiply it by the number of people
For #5 you multiply the two numbers. For #6 you
